ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 519,292, dated May 1,1894.

Application iiled February 9, 1 894.

To all whom it may concern:

Be it known that I, GEORGE QUACKENBUSH, a citizen of the United States, and a resident of Whitehall, in the county of Trempealeau and State of Wisconsin, have invented certain new and useful Improvements in Elevators;

and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part'of this specication.

My invention relates to improvements in elevators, and is designed more particularly for depositing ice in ice boxes, although it may be employed with advantage in elevat` ing building material during the construction of buildings, and for many other purposes.`

The object of` the invention is to provide an elevator of the above description which shall possess superior advantages with respect to simplicity and efficiency in operation.

The invention consistsin the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of an elevator constructed in accordance with my invention. Fig. 2 is a central longitudinal section of the same.

In the said drawings the reference numeral 1 designates two stout beams, rigidly connected together by cross beams 2. The lower ends of these beams are beveled so that when the beams are set at the proper inclination said ends will rest square upon the ground or Hoor. The inner edges of these beams are cut away forming tracks 8, which" are provided with rails 4 upon which the carriage 5 travels. It will be noted, that these tracks at their upper ends curve upwardly and then downwardly, as seen in Fig. 2, and are provided with a shaft 6, on which is journaled a roller 7. At their upper ends the beams are also provided with a shaft 8 and roller 9, located slightly in advance of roller 7. The upper ends of the beams are beveled and provided with hooks 10, which engage with the box or other object, in which the materials or sub- 5o stances4 elevated are to be deposited, and serve serial No. 499.663. (No moan.)

to hold the apparatus in place. Upon their upper sides the beams are provided with iiat springs 12, which project forwardly over the front beveled ends ofthe beams, and their object is to automatically throw the carriage back after its load has been dumped as will be hereinafter more fully set forth.

The numeral 5 designates the carriage comprising the rectangular platform 14, provided on its under side with blocks 15, provided with front and rear axles 16, on which are journaled wheels 17. It will be noted` that the front wheels are slightly smaller than the rear wheels, so that the platform will occupy an inclinedposition with respect to the beams. Secured to the under side of these blocks are hooks 18, which are adapted toengage with the roller 7, when the carriage is elevated and limit or check the movement of Upon the upper side of the platformnear each side are secured two blocks 19, the upper sides of which are beveled and to these beveled sides are secured rails 20, bent upwardly at or near their centers forming shoulders 2O*l and then 'downwardly forming tracks 2Gb on which the articles or objects to be ele vated are slid onto the platform, the shoulder 20a, at the center preventing the objects from slipping or sliding back. Y Secured to the said platform is a rope or cable 23, which passes over rollers 7 and 9, and is then carried down to a windlass 24, provided with a crank 25, ratchet 26 and pawl 27.

said carriage. f

The operation is as follows: The beams are connected by means of the hooks lO with the box or other object in which the articles elevated are to be deposited, with the carriage at the bottom thereof and the lower ends of the rails resting on the ground or floor'. A

block of ice or other object can now be readily slid on the rails or tracks onto the platform, the shoulders 2Oab holding the same in place and preventing it from sliding back. carriage is now elevated by vmeans of the rope and windlass until the front wheels run olf the ends of the curved tracks,

form will be tilted by the weight of the load, so as to engage with and depressthe springs 12. This tilting of the platform will cause the load toA slide off the same into the box or The when the plat- Ime other receptacle, when the resiliency of the springs will elevate the tilted end of the carriage causing it to return to normal or the p0- sition it occupied before being tilted. The carriage will now descend by gravity to the bottom of the apparatus, ready to receive `another load. It will be seen that when the to descend or be lowered after the load is dumped.

As before stated, while the invention is primai-ily intended to deposit ice in ice boxes,

.it can be used with great advantage in elevating purposes generally.

Having thus described my invention, what I claim is- 1. 1n an elevating apparatus of the character described, the combination with the beams having their upper ends beveled, the forwardly extending springs'secured to the said beams and the tracks having their upper ends curved, of thecarriage, the rope or cable secured thereto and the windlass; substantially as specified. v

2. `In an elevating apparatus, the combination with the beams, having beveled upper ends, the forwardly extending springs, securedV to said beams, the transverse rollers and the tracks having curved upper ends, of thecarriage, having hooks on its under side adapted to engage with one of said rollers,

the rope or cable secured to said carriage and tho Windlass; substantially as specified.

3. In an elevating apparatus, the combination with the beams, having their upper ends beveled and provided with forwardly projecting springs the rollers and the tracks having their upper ends curved, of the carriage comprising the Wheels, the platform, and the bent rails secured to said platform and the rope or cable and windlass substantially as specified.

4. In an elevating apparatus, the combination with the beams having their upper ends beveled and provided with forwardly extending springs, the rollers, the tracks having their upper ends curved, and the rope or cable i and the windlass, of the carriage comprising the platform, the wheels, the hooks, for limiting the movement of the carriage and the bent rails secured to the platform; substantially as described.

5. A carriage for an elevating apparatus comprising the platform, the wheels and axles, and the rails 20, secured to said platform and formedwith should ers 202L and tracks 20D; substantially as specied.

6. A carriage for an elevating apparatus, comprising the platform, the wheels and axles, the hooks `on the under side, and the rails 2O secured to said platform and bent at or near their centers to form shoulders 2Ofh andtracks 20h; substantially as specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

GEORGE QUAOKENBUSH.
